Brief description of the drawings
Fig. 1 is the structural representation of the inspection electric aerodyne including brake gear according to embodiments of the invention.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment and reference
The present invention is described in more detail for accompanying drawing.
Various embodiments of the present invention propose a kind of brake gear and inspection electric aerodyne, can be safer efficiently to high pressure
Transmission line of electricity carries out inspection and upkeep operation.
Embodiment according to an aspect of the present invention is there is provided a kind of brake gear, for leading along ultra-high-tension power transmission line
The inspection electric aerodyne of line inspection, including：
Brake lever, it is installed in rotation on articulated section in the main body of inspection electric aerodyne, and including positioned at described
The inner and outer end of the two opposite sides of articulated section；
Brake block, it is installed to the inner of the brake lever, and conductor part residing for the roller in inspection electric aerodyne
Lower section；
Control member, it is connected to the outer end of the brake lever；
Spring, it is connected between the main body of the brake lever and inspection electric aerodyne, the spring and the brake lever
Connecting portion is located away from the articulated section of the brake lever；
Wherein, when the control member is enabled and rotates down the outer end of the brake lever, the brake lever is driven
The inner on the brake block upwards motion and wire lower surface is compressed to perform brake operation；When the control member is disabled
When, the spring promotes the brake lever to rotate backward and the brake block is departed from wire.
So, including the brake gear inspection electric aerodyne (may be simply referred to as driving) pass through wire ascender line roll
The forward and backward roller of operation realizes walking, and operating personnel is hung in the flap seat below wire and by the brake gear
The control of control member and realize the skidding to driving.Wherein, wire is constrained in the outer circumferential edges of forward and backward roller
Annular groove in (to prevent forward and backward roller from departing from from wire), and in top roller (i.e. front wheel or rear roller) and
Between the brake block of lower section (wherein brake block is aligned with front wheel or is aligned with rear roller).In the case, above wire
The front wheel or rear roller of operation are pressed on wire from top, and when control member is enabled, the brake block below wire from
Lower section compress wire, thus make roller and brake block respectively from upper and lower clamp wire so that by wire " holding " at the two it
Between so that the frictional force increase of roller and wire, it is achieved in brake operation.This brake modes by increasing frictional resistance
It will not act directly on roller and produce risk of the roller from wire dropping, thus more steady and safety of braking.
So, the inspection electric aerodyne under driven by power (for example can be self-powered, preferably power supply, which may be provided at, hangs
In seat) operation is easily operated by the operating personnel in flap seat, not only power is big (thus can improve the speed of service and operation effect
